Complement C1q, Human
Description:
C1q is serum glycoprotein of 18-polypeptides chains consisting of three non-identical subunits, A (29kD), B (26kD) and C (246aa, 19kD) in molar ratio of 1:2:2. Detection of C1q in serum, in serum-C1 and within immune complexes; inhibits hemolytic activity of C1 by binding to C1q in the liquid phase (antibody concentration necessary to inhibit 50% of hemolytic activity in the fluid phase is ~0.85ug/ml). With C1 bound to immune complexes a dose dependent increase of C1 activity was observed at antibody concentrations of 1.5ug/ml. Useful for detection of C1q-bearing immune complexes in patients with rheumatic disorders.

Applications:
Suitable for use in ELISA, Western Blot and Inhibition experiments (e.g. hemolytic activity). Other applications not tested.

Recommended Dilution:
Western Blot: 1:10-1:50 (ECL method). Incubate for 1hour at RT.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
